If you're not into or concerned with bodybuilding, I wouldn't go too far conflating strength and fitness with muscle size. If you play sports or do other activities where strength is advantageous, then keep getting stronger and let your muscles do what they will. If you like what you see in the mirror (or more importantly, would dislike what you'd see in the mirror should you continue to grow), then maybe you stay where you're at or dial it back a bit to maintain.

I think that muscular women are beautiful. I dont think that you should get really cut, because that is not healthy for women and men as well. But keep your muscles toned not tone down if that is what you want to do.

I find it fine and am a guy, i am into girls who do crossfit. Women, or young girls or teens might always look or find a over musculer women to be gross. Though if u like it and find it fine then u shouldnt worry to much about wat other people think.
